Australia has six states—New South Wales (NSW), Queensland (QLD), South Australia (SA), Tasmania (TAS), Victoria (VIC) and Western Australia (WA)—and two major mainland territories—the Australian Capital Territory (ACT) and the Northern Territory (NT). In most respects these two territories function as states, except that the Commonwealth Parliament has the power to modify or repeal any legislation passed by the territory parliaments.

Australia is a wealthy country; it generates its income from various sources including mining-related exports, telecommunications, banking and manufacturing.It has a market economy, a relatively high GDP per capita, and a relatively low rate of poverty.
